KINGMAN, Kan. (AP) — A former Kansas lawman returns to the witness stand to answer questions about what happened during the early morning hours leading to the shooting death of his wife.

The first-degree murder trial of Brett Seacat resumes Friday with the 37-year-old Kingman man testifying in his defense. He is charged in the April 2011 shooting death of Vashti Seacat 16 days after she filed for divorce. He also faces aggravated arson and two counts of child endangerment for allegedly setting fire to the house while the couple’s two children were sleeping. The children were not harmed.

The defense contends Vashti Seacat killed herself.

Seacatt testified for nearly two hours Thursday about his work as a former police instructor and sheriff’s deputy, the divorce and his movements the day before the fire.
